Could someone advise/guide me on how to setup a slow SPI clock using the SPI lib on a Teensy LC for <400kBaud rates?
I wish to use a 'slow' SD Card module (from 2004! :/) on a Teensy LC. (I often like trying stuff out of my old scrap collection)
The spec describes: synchronous 8-bit data transmission, MSB first. For initialization <400KBaud. A clock cycle is also required to read in data from the memory cards, possibly by outputting a dummy byte.
Many thanks
Peter
